Using Komatsu WA380-1 Wheel Loader Parts Catalog
This Komatsu WA380-1 wheel loader parts catalog helps you locate aftermarket replacement parts by machine system and assembly. Its current coverage contains 200 assembly listings across 11 source sections. The navigation groups related sections for easier browsing; available choices include Engine, Work Equipment, Torque Converter And Transmission, Drive Shaft, Differential And Wheels and Frame And Guard.
Choose the section relevant to your repair, then compare the full Komatsu WA380-1 model designation, machine serial range and any engine or attachment information on the assembly page. Model suffixes, serial breaks and configuration notes remain important even where two diagrams look similar.
The published engine listings identify SA6D110-1Q (engine serial 54352-UP) and SA6D110-1U (engine serial 54352-UP). These are catalog applications, not a claim that every machine in this model series uses the same engine configuration.
Use the part-number links to inspect listed store products, or select the required parts and quantities to prepare a quote. Only the published sections are shown here; the catalog does not imply that every original book section or machine configuration is available.

Illustration is schematic and not to scale. Confirm actual machine dimensions, attachments and transport position before arranging haulage. Operating weight and shipping weight are different measurements; neither is established by this diagram.
